python won't recognice my function

I have this weird problem where my program will give me this error message when I run my code:

Traceback (most recent call last):
   File "\\srv-fons-02\USV_Home$\6357\inf\Phyton\classes test 1.py", line 38, in <module>
     time = Time(7, 61, 12)   File "\\srv-fons-02\USV_Home$\6357\inf\Phyton\classes test 1.py", line 8, in __init__
     self = int_to_time(int(self)) NameError: name 'int_to_time' is not defined

It tells me the function int_to_time isn't defined, while it is. I also only get this problem in my __init__ and not in other places where I use it (add_time that gets used in __add__ for example). I don't know why it does work with some functions. I have tried canceling the int_to_time() in __init__ and didn't get an error message even tough I use __add__).

If anybody could help me that would be great, cause I am stuck atm.

This is my code:

class Time:
    def __init__(self, hour=0, minute=0, second=0):
        self.hour = hour
        self.minute = minute
        self.second = second
        if not 0 <= minute < 60 and 0<= second < 60:
            self = int_to_time(int(self))

    def __str__(self):
        return '%.2d:%.2d:%.2d' % (self.hour, self.minute, self.second)

    def __int__(self):
        minute = self.hour * 60 + self.minute
        second = minute * 60 + self.second
        return int(second)

    def __add__(self, other):
        if isinstance(other, Time):
            return self.add_time(other)
        else:
            return self.increment(other)

    def __radd__(self, other):
        return other + int(self)


    def add_time(self, other):
        seconds = int(self) + int(other)
        return int_to_time(seconds)

    def increment(self, seconds):
        seconds += int(self)
        return int_to_time(seconds)
    """Represents the time of day.
    atributes: hour, minute, second"""

time = Time(7, 61, 12)

time2 = Time(80, 9, 29)

def int_to_time(seconds):
    time = Time()
    minutes, time.second = divmod(seconds, 60)
    time.hour, time.minute = divmod(minutes, 60)
    return time


print(time + time2)
print(time + 9999)
print(9999 + time)

The fact that the invocation of int_to_time is made before the definition has been seen is the problem.

You initialize two Time objects before defining int_to_time:

time = Time(7, 61, 12)

time2 = Time(80, 9, 29)

def int_to_time(seconds):
    time = Time()

and inside Time.__init__ you invoke int_to_time after a certain condition. If that condition is met, the call to int_to_time will fail.

Just moving the initialization after the definition suffices. Since int_to_time also seems closely related to your Time class it wouldn't be a bad idea to define it as a @staticmethod for that class and drop all worries about when the definition is made.
